We (the company 'us') have left home base behind for a few weeks to 3 months, with an occasional 'speed tour' back with no leisure to listen....
Absence can make one's ears 'shift', imh experience. Having been stuck listening to everything from jobsite machinery to supermarket music, and the random 'basser' next to in traffic, having one's gear go chilly may not be the main issue in mind or at ear.
Although passages, rifts, and lyrics may be in mind, the experience involved with ones' choice of musical means may seem to have a 'shift' in the comprehension of your personal preferences of medium methods.
It sometimes requires a day or three to 'recall' what you liked (or didn't) about it all. Bear in mind that I'm referring to longer periods of 'withdrawals' ', as opposed to 3 day weekend jaunts....but your experience likely varies, the way most details do..
